| Application No. | Application Title | Issue Date |
| 20120082282 | METHODS RELATING TO PHOTONUCLEAR DETECTION Methods relating to photonuclear detection are disclosed. A method of operating a photonuclear detection system may include transmitting photons toward a container for a duration of a first time period. The method may further include waiting for a duration of a second t... | 04/05/2012 |
| 20110096886 | Method and System for Detecting Special Nuclear Materials A method and system for detecting special nuclear materials are disclosed. Said method and system detect the special nuclear materials by making use of the photofission characteristic and thermal neutron induced fission characteristic thereof. In one preferred embodimen... | 04/28/2011 |
| 20100046690 | Apparatus and Method for Detection of Fissile Material Using Active Interrogation A system for interrogating a package, container, vehicle, or similar examination article for the presence of nuclear material. The system typically includes a source of photo-fission energy configured to irradiate the examination article and trigger fission of a fissile... | 02/25/2010 |
| 20090262882 | DISTINGUISHING BETWEEN CLASSES OF FISSIONABLE MATERIAL A first pulsed beam of charged particles from a particle accelerator is accelerated toward a first target that is configured to emit a fast neutron beam in response to being struck by an accelerated particle such that the fast neutron beam is directed toward a physical ... | 10/22/2009 |
| 20090175401 | NON-INTRUSIVE METHOD TO IDENTIFY PRESENCE OF NUCLEAR MATERIALS USING ENERGETIC PROMPT NEUTRONS FROM NEUTRON-INDUCED FISSION Methods and systems for non-intrusively detecting the existence of fissile materials in a container via the measurement of energetic prompt neutrons are disclosed. The methods and systems use the unique nature of the prompt neutron energy spectrum from neutron-induced f... | 07/09/2009 |
| 20080240329 | DETECTING SPECIAL NUCLEAR MATERIALS IN SUSPECT CONTAINERS USING HIGH-ENERGY GAMMA RAYS EMITTED BY FISSION PRODUCTS A method and a system for detecting the presence of special nuclear materials in a suspect container. The system and its method include irradiating the suspect container with a beam of neutrons, so as to induce a thermal fission in a portion of the special nuclear mater... | 10/02/2008 |
| 20060291606 | Micro neutron detectors Micro neutron detectors include relatively small pockets of gas including a neutron reactive material. During use, under a voltage bias in a neutron environment, neutron interactions in the neutron reactive material are seen to occur. Ultimately, electron-ion pairs form... | 12/28/2006 |
| 20050220246 | Method and apparatus for detecting high-energy radiation using a pulse mode ion chamber A method for measuring high-energy radiation includes applying a voltage pulse to electrodes in an ion chamber filled with a gas capable of forming charged ions by the high-energy radiation; measuring an ion current signal related to ion currents induced by the voltage ... | 10/06/2005 |
